node.h: Reduce struct size to fit with Ruby object size (five VALUEs)

2021-06-17T17:34:27+00:00

by merging `rb_ast_body_t#line_count` and `#script_lines`.

Fortunately `line_count == RARRAY_LEN(script_lines)` was always
satisfied. When script_lines is saved, it has an array of lines, and
when not saved, it has a Fixnum that represents the old line_count.

ast.rb: RubyVM::AST.parse and .of accepts `save_script_lines: true`

2021-06-17T17:34:27+00:00

This option makes the parser keep the original source as an array of
the original code lines. This feature exploits the mechanism of
`SCRIPT_LINES__` but records only the specified code that is passed to
RubyVM::AST.of or .parse, instead of recording all parsed program texts.

NODE markability should not change by nd_set_type

Change NODE layout for pattern matching

2020-11-01T07:19:07+00:00

I prefer pconst to be the first element of NODE.

  Before:

       | ARYPTN | FNDPTN | HSHPTN
    ---+--------+--------+-----------
    u1 | imemo  | imemo  | pkwargs
    u2 | pconst | pconst | pconst
    u3 | apinfo | fpinfo | pkwrestarg

  After:

       | ARYPTN | FNDPTN | HSHPTN
    ---+--------+--------+-----------
    u1 | pconst | pconst | pconst
    u2 | imemo  | imemo  | pkwargs
    u3 | apinfo | fpinfo | pkwrestarg

include/ruby/backward/2/r_cast.h: deprecate

2020-08-27T06:03:36+00:00

Remove all usages of RCAST() so that the header file can be excluded
from ruby/ruby.h's dependency.

Remove unused struct member

2020-08-04T00:01:13+00:00

I accidentally added this in 35ba2783fe6b3316a6bbc6f00bf975ad7185d6e0,
and it's making the size of RVALUE be too big. I'm sorry! orz

rb_{ary,fnd}_pattern_info: Remove imemo member to reduce memory usage

2020-08-01T16:04:06+00:00

This is a partial revert commit of 8f096226e1b76f95f4d853d3dea2bc75eeeb5244.

NODE layout:

  Before:

       | ARYPTN | FNDPTN | HSHPTN
    ---+--------+--------+-----------
    u1 | pconst | pconst | pconst
    u2 | unused | unused | pkwargs
    u3 | apinfo | fpinfo | pkwrestarg

  After:

       | ARYPTN | FNDPTN | HSHPTN
    ---+--------+--------+-----------
    u1 | imemo  | imemo  | pkwargs
    u2 | pconst | pconst | pconst
    u3 | apinfo | fpinfo | pkwrestarg

Use a linked list to eliminate imemo tmp bufs for managing local tables

2020-07-27T19:40:01+00:00

This patch changes local table memory to be managed by a linked list
rather than via the garbage collector.  It reduces allocations from the
GC and also fixes a use-after-free bug in the concurrent-with-sweep
compactor I'm working on.

Use ID instead of GENTRY for gvars. (#3278)

2020-07-03T07:56:44+00:00

Use ID instead of GENTRY for gvars.

Global variables are compiled into GENTRY (a pointer to struct
rb_global_entry). This patch replace this GENTRY to ID and
make the code simple.

We need to search GENTRY from ID every time (st_lookup), so
additional overhead will be introduced.
However, the performance of accessing global variables is not
important now a day and this simplicity helps Ractor development.
